3 Why Behavioral Finance?
Correctness of security prices Just because researchers cannot exploit anomalies, does it mean markets are efficient? Are investors really rational? How about human psychology?

4 Behavioral Critique How do real people behave? Irrationality
Investors do not always process information correctly and infer incorrect probability distributions about future rates of return Even given a probability distribution of returns, they often make inconsistent or systematically suboptimal decisions.

5 Behavioral Biases Even if information processing were perfect, many studies conclude that individuals would tend to make less-than- fully-rational decisions using that information. Framing (Decisions seem to be affected by how choices are framed) (An individual may reject a bet when it is posed in terms of the risk surrounding possible gains but may accept that same bet when described in terms of the risk surrounding potential losses)

6 Behavioral Biases Mental accounting (investment account vs. child’s savings account) (gambling & house money) Regret Avoidance (conventional vs. unconventional decisions) (blue chip vs. start up)
